Q: What Are the Maintenance Requirements for a Power Brake Booster Unit?
A: Periodic inspection of the vacuum hose and case is all that is required for maintenance. To check operation, depress the brake pedal with the engine off and start the engine. To remove the power brake booster, remove the master cylinder and disconnect the vacuum hose and pushrod. To install, place the booster into position, connect the pushrod and master cylinder, connect the Brake Lines, and tighten all fitting nuts.
